Half an hour later, Zhu Ganglie followed the traces left by Twenty Yang Sheng and the other disciples of the Purple Cloud Sect and soon came to a medium-sized hall.

I saw a golden plaque hanging in the center of this hall, which read the words "Dark Auxiliary Palace", which was exactly the same as the stone tablet on the path outside.

Similarly, the ban on the protection of this hall has been broken by the disciples of the Purple Cloud Sect such as Twenty Yang Sheng, and Zhu Ganglie, who was standing outside the main hall, could vaguely hear a fierce fighting sound coming from the depths of the main hall, as well as a roar of some kind of demonic beast, and even Zhu Ganglie, who was standing outside the hall, had a feeling of numbness in his ears and eyes, which showed how fierce the battle in the hall was.

Recalling the several demonic beast corpses he had seen along the way, they were all at the peak of their strength in the late stage of the Blood Condensation Realm, which showed that the strength of the Purple Cloud Sect disciples such as Twenty Yang Sheng was strong and difficult to deal with.

Therefore, Zhu Ganglie did not rush into the dark sub-hall, but stood outside the dark hall and thought quietly for a while, glanced at the side hall next to the dark sub-hall, hid his appearance, and quietly sneaked in.

After a pillar of incense, Zhu Ganglie searched this side hall, except for some stone tables, stone platforms, and stone pillars, he didn't find anything useful, it seems that this side hall has been shaved clean by Twenty Yang Sheng and other disciples of the Purple Cloud Sect, and there is not even a single hair left.

However, Zhu Ganglie found a secret door in the back of the side hall, Zhu Ganglie carefully pushed it open, but he could faintly hear a fighting sound from the secret door, Zhu Ganglie got closer and listened carefully, but found that the fighting sound was made by the group of Ziyun Sect disciples of Twenty Yang Sheng, looking at the dark path in front of him, Zhu Ganglie's eyes showed a thoughtful look, and then showed a trace of inexplicable excitement, as if he had a plan in his heart.

Zhu Ganglie cautiously stepped into the stone steps of the dark passage, and found that although the dark passage was a little dim, it was not pitch black, because the stone walls on both sides of the dark passage were inlaid with a diamond-shaped pale yellow stone, which was not a spirit stone, but it could emit a faint yellow light to illuminate the stone steps in the dark passage.

Zhu Ganglie cautiously groped in the dark passage for a while, and found that there was no hidden mechanism, so he walked towards the depths of the secret passage with confidence.

The more he walked forward, the closer the sound of fighting came from his ears, and he could faintly hear the angry shouts of the disciples of the Purple Cloud Sect.

Not long after, Zhu Ganglie had already come to a stone gate along the dark path, at this time, the shouts of the disciples of the Purple Cloud Sect were already clearly audible, according to Zhu Ganglie's speculation, behind this stone gate was probably the main hall of the dark secondary hall.

Zhu Ganglie hesitated for a while, suddenly made a decision, cautiously came to the stone gate, with a slight force, the stone door moved, and made a faint friction sound, which seemed weak and inaudible in the hall where the battle was extremely fierce, with Zhu Ganglie's strength, it was easy to push open this stone door, but if he did that, Zhu Ganglie would definitely expose his traces, and he could only move the stone door little by little.

After a while, Zhu Ganglie had already moved the stone door out of a gap that only allowed one person to pass through, and the bright light in the main hall had already shot into the dark passage, pulling Zhu Ganglie's shadow to the elders.

Zhu Ganglie held his breath and stared, tiptoed out of the dark passage, and dodged close to a huge stone pillar.

A burst of "ping-pong" fighting sound occurred in front of the side of the stone pillar where Zhu Ganglie was hiding, close at hand, Zhu Ganglie did not dare to use his demon sense to detect the battle situation in the hall, and could only use the corner of his eye to look at the entire hall.

According to Zhu Ganglie's observations, the distribution of the entire hall was speculated.

The space of the whole hall is very wide, there are eight huge golden stone pillars in the hall, on the left and right, four on one side, supporting the entire Lingjin sub-hall, and Zhu Ganglie's position at this time is the last stone pillar behind the left side of the main hall, and the walls on both sides of the sub-hall are depicted with some strange flowers and plants, and the stone relief statues of fierce beasts and monsters are extremely realistic, as if they are about to break out of the wall.

In the middle of the main hall is an open space, which is where the hall in the hall is located, and the battle at this moment is taking place in the hall, only more than ten zhang away from Zhu Ganglie.

Zhu Ganglie, who was hiding behind the stone pillar, cautiously poked his head out and looked at the battlefield in the hall with the corner of his eye.

I saw that the five disciples of the Purple Cloud Sect in the middle of the blood coagulation period, under the leadership of Twenty Yang Sheng, were fighting fiercely with a black demon beast that looked like a snake but not a snake, Zhu Ganglie looked at the demon beast and found that this snake-shaped demon beast was covered with black scales all over its body, and two fist-sized bulges were faintly displayed on its head, and its mouth was densely covered with sharp teeth, like rows of flying swords, the cold light was shining, and it was scattered.

This is a snake, it is clearly a black dragon that is about to turn into a dragon, and its body is about ten zhang long.

I saw that this black dragon had already reached the strength of the early stage of the Demon Pill Realm, but the aura on his body was extremely unstable, and he was in the early stage of the Demon Pill Realm for a while, and then he fell to the peak of the Blood Condensation Realm.

I saw the black Jiaolong coiling its body, the dragon's eyes, revealing a cold color, and opened its mouth to spit out a black flame, which made the temperature in the entire auxiliary hall quickly rise and become extremely hot, forcing several disciples of the Purple Cloud Sect beside Twenty Yang Sheng to retreat, while Twenty Yang Sheng was holding a colorful umbrella-shaped defensive spirit weapon, which emitted a five-colored glow under the control of Twenty Yang Sheng, dazzling and abnormal, withstanding the black flames spewed by the black dragon.

Twenty Yang Sheng controlled a golden giant sword about three zhang long, shining with golden light, and slashed at Jiaolong's head with great sharpness, and the rest of the Ziyun Sect disciples controlled several flying swords, constantly stabbing at the body parts of the black dragon, making a series of "gold and iron resonance" sounds, drawing sparks on the dragon's black scale armor, but they couldn't hurt the dragon in the slightest.

Seeing the golden sword of Twenty Yang Sheng splitting in, Jiaolong's humanized eyes showed a trace of solemnity, raised the tail of Jiao, and slapped the sword body of the golden big sword as fast as lightning, with a "bang" explosion, the black Jiaolong slapped the big sword of Twenty Yang Sheng's envoy a little off, so that Twenty Yang Sheng slashed at the golden giant sword of Jiaolong's head, and a sword slashed on the stone slab in the hall, but he didn't know that this stone slab was made of various materials, and the powerful sword did not leave a mark on the stone slab, only a burst of sparks splashed out.

And Zhu Ganglie noticed that after the black dragon slapped Twenty Yang Sheng's golden giant sword, there was a faint tremor on its tail, obviously Twenty Yang Sheng's sword was not so easy to catch.

After shooting the golden giant sword of Twenty Yang Sheng, the black dragon spewed out another black flame, shooting straight towards Twenty Yang Sheng, although Twenty Yang Sheng used the five-color spiritual light emitted by his umbrella-shaped defensive spirit weapon to block it, but Zhu Ganglie was still keenly aware that the five-color spiritual light emitted by the umbrella-shaped spiritual weapon was getting dimmer and fainter, and I was afraid that if it continued like this, this defensive spiritual weapon would be burned by the flame power of the black dragon.
